HOW FAR CAN YOU GO ON FLAT REAR TYRE

[mtread]

Oh i see, it's not something i've ever used so not familiar with it. Handy to know though.Are you risking anything with the Optimate when charging though, with the higher fuse?And out of curiosity where does the lead sit for easy access?

Given the Optimate self regulates the amount of current it uses to put through, I'm guessing upping from 5 to 10 won't be an issue. But I'm no electrician.
The only issue might be a short across the connector terminals, but again I'm hoping a 10a is sufficient.
On the Fazer it's near the headstock, protected by a cap. Next to the same type of connectors for the heated grips

I’ll bear in mind the possible 10 amp fuse requirement. I’ve used my Airman on maybe 6 occasions using the Optimate lead with no blown fuses however. I have had the engine running on each occasion, not that that should make any difference. Just my paranoia regarding not flattening the battery. On my thou. the lead is clipped to the rear brake hose close to the master cylinder.

Makes total sense to me to just let the engine tickover when using the pump.
When i get a chance and another pair of hands to help i'll find out what the Airman uses when it's switched on and add it to the battery voltage readings link.

Just checked and found that the Airman also has its own inline 10 amp fuse. Should have spotted that first  :rolleyes
My Optimate lead is at the headstock on the Fazer because I occasionally used it to power a Tomtom.
My Tiger has a permanent satnav connection, so like Robbo, the Optimate/Airman lead is more safely attached to the rear master cylinder, out of the way.
